Dontech Ancillary Services

Dontech will integrate its optical products into electronic displays (e.g., LCDs) and bezels for its customers. Commercial off the shelf (COTS) displays can be customized by Dontech to improve the optical performance, operating thermal range, EMI/RFI emissions/susceptibility, and mechanical durability. Dontech enhanced display solutions allow the display to function properly in demanding environments, such as direct sunlight, low or high temperatures, or military environments.

Dontech’s engineering and manufacturing facilities are located in Doylestown, PA, USA. Primary markets include military, avionics, medical, industrial and electronic instrumentation. For over 35 years Dontech has supplied its products and services to an international customer base.
